Beers at hockey arenas are pretty expensive, so it's a shame when one is ruined by a flying earpiece.

During the Boston Bruins' 3-2 shootout win over the Toronto Maple Leafs at TD Garden Monday night, Bruins assistant coach Geoff Ward took out his earpiece and tossed it over his shoulder. The earpiece sailed over the glass and landed in what appears to be an unsuspecting fan's beer.

Perfect trajectory. Perfect timing. Perfect reaction.

UPDATE: While it appeared that Ward tossed his earpiece over the glass, it turns out he wasn't the guilty party.

On Tuesday, Bruins center Tyler Seguin set the record straight. Seguin tossed his smelling salts into the crowd and the camera angle made it appear as if the object was coming from Ward. Mystery solved.
